BGP - Taking Long time to Announce Subnets

RouterOS Forwarding Protocols
1

Hi,

I’m running a small home network using a CCR1009-7G-1C-1S+ Router

2 x 1Gb External Fibre Access
3 x BGP IPv4 Peers (two of which via a GRE tunnel)
3 x BGP IPv6 Peers (two of which via a GRE tunnel)

All are sending me a full Table.

I’m announcing two IPv4 /24 and a 1 x /IPv6 via my Public AS Number.

I have noticed that if we shutdown all the BGP or even reboot the router, it takes about 20 minutes for the prefixes that I’m announcing to be sent upstream.

its like the BGP processes the downstream routes first before it sends the prefixes we are sending.

this takes around 22 minutes to complete.

Is there a way to reduce this time?

You are a lucky guy.
The CCR2004 with two IPv4 and two IPv6 took around 40min to announce my networks.

Recently we upgarded our edge routers to 2216 and now seems to be better, no more long waiting times for the announces to propagate.

This happening on certain RouterOS v7 versions, regardless of hardware model.

For me it happens to IPv6, it takes like 10-20 minutes to advertise my prefixes after a reboot.

6-10 minutes in my config with 3 fw neighbours.

same problem here.

For no reason, the announcements take more than 5 minutes to start propagating.

Router OS version: 7.14
